10 points - What is the 8th term of the sequence? 8, 24, 72, 216...

For functions, x’s can’t repeat, so looking at the first problem, C is the only one where the first number in each coordinate (x,y) doesn’t repeat.

For the second, x = -2 means that no x is always -2 matter which y you would look at. So x’s repeat and it forms a vertical line. So it is not a function

Solve the system of equations: y= 2x - 5 y=x^2-5 Apex

arlik [135]

Answer:

A is the answer

Step-by-step explanation:

(0, -5):

-5 = 2(0) - 5 >>> -5 = -5

-5 = (0)^2 - 5 >>> -5 = -5

(2, -1):

-1 = 2(2) - 5 >>> -1 = 4 - 5 >>> -1 = -1

-1 = (2)^2 - 5 >>> -1 = 4 - 5 >>> -1 = -1

A researcher reports a 98% confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be [0.34,

Fantom [35]

Answer:

$0.34 \leq p \leq 0.38$

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

Step-by-step explanation:

For this case we have a confidence interval for the proportion of Drosophila in a population with mutation Adh-F to be given by:

$0.34 \leq p \leq 0.38$

For this case we can conclude that with 98% of confidence the true proportion of Drosophila in a population would be between 0.34 and 0.38.

But that doesn't means that we have 98% of PROBABILITY that the true proportion would be between 0.34 and 0.38, because we are constructing a confidence interval with sample data and we can't analyze this using probability.

Then the best answer is:

2. False

How do you solve y=x-3 and Y= -x +5

artcher [175]

Answer:

The answer is 4

Step-by-step explanation:

Set them equal so it would be X-3= -X+5 then add the negative X to get

2x-3=5 then add the -3 to 5 and get

2x=8 then divide 2 from both sides to get

x=4
